Referring more specifically to the drawings illustrating the'preferredembodiment of my. invention, it should be noted that Fig. 1, which ismore or less diagrammatical in form, shows an automobile door, agenerally indicated at I having a main vertical sliding sash II and aswinging ventilator window I2. The sliding sash II is connected to themain unit I3 which is mounted in the lower portion of the door by meansof a rack member I4 which is connected to the lower frame I 5 of saidsash. This rack raises and lowers the sash I I from mechanism which willbe fully described later and which is contained with the unit I3. Theventilator I2 is swung in alternate directions, as when opening andclosing same, by means of the rod I6 which is also cbnnected with theunit I3. Also located in the door but not shown in Fig. 1, is thecontrol lever,bet-

ter shown in Figs. 28 to 31, which also connects with the unit I3 forthe purpose of operating the electrical switch elements.

The heart of the mechanism is located in the unit I3 as illustrated inFigs. 18 to 2'7, and Figs. 6 to 10 inclusive illustrate the connectionbetween the mechanism shown in Figs. 18 to 27 and the apparatus whichoperates the switch mechanism which is positioned bymeans of the controlapparatus shown in Figs. 28 to 31 inclusive.

The complete driving mechanism and switch control mechanism is containedin the unit I3 in which is mounted a reversible electric motor I? themotor drive shaft I8 of which is coupled at I9- to a worm gear 20 whichengages a worm wheel 2I transversely mounted in the unit IS. The sidesof the unit I3 are indicated by the numeral 22 which indicates the frontside, as viewed from the interior of the automobile, and 23, as viewedfrom the opposite side of the mechanism. The window sash II is raisedand lowered y 1 621 of the rack I4 which is engaged with the pinion 24when the pinion 24 rotates in a right or lefthand direction, as the casemay be. In a similar manner the ventilator window I2 will swing to oneside or the other, as the case may be, when the rack 25 is moved in thecorresponding direction. By an inspection of Fig. 4 it wil be observedthat a second pinion 25 is engaged with the teeth of the rack member 25,the major axis of the pinion 26 and the pinion 24 being the ame. It willthus be seen that when the pinion 26 rotates, the rack 25 will move in ahorizontal direction, and due to the fact that the rack 25 is engagedwith the gear 21 which is directly connected with the pinion 28 which iengaged with the gear 29 which is directly connected with the rod I6,the ventilator window I2 will swing to the right or left, as the casemay be when the rack 25 is moved.

The unit disclosed in Figs, 18 to 27 inclusive comprises a multipledriving mechanism which operates the pinions 24 and 26, said pinionsbeing independently operated clockwise or counterclockwise by means ofthe worm wheel 2| which operates clockwise or counter-clockwise from theelectric motor Il. Inother words, the pinion 24 which engages the rackI4 will raise or lower the sash II by means of the reversible motor I1,and in a similar manner, the pinion 26 will operate the horizontal rackto the right or left, as the case may be, from the said motor I 1. Bothpinions 2 1 and 26 are driven forward or reverse by means of the wormwheel 2| only if the mechanism adjacent the pinion in question andbetween the said pinion and the worm wheel 2I is in a driving position;otherwise either of said pinions will be disengaged from the worm wheel2I. As will be noted, as the description progresses, both of the pinions24 and 26 cannot be driven from the worm wheel 2I at the same time;therefore it will be observed that the apparatus mounted on each side ofthe worm wheel 2I constitutes a friction clutch mechanism and the entireunit, asset forth in Figs. 18 to 2'7, constitutes a multiple clutch.

In the description of the apparatus, Figs. 18'

side being a duplicate and operating in an identi cal manner exceptingas controlled by other apparatus. Figs. 19 to 25 inclusive illustratethe internal mechanism of one side of the multiple clutch in asuccessive elimination of parts as removed from the outer side adjacentthe pinion 24 inwardly to the face of the worm wheel 2i. In Fig. 19 thefirst disc 32 is provided with a plurality of slots BI and segmentmembers 32. The disc 36 is freely journalled about the shank portion 33of the pinion 2 3, see Fig. 26; Fig. 20 shows the mechanism directlyunder the disc 30. The portion indicated at 34 is provided with tappedholes 35 and 35 and adapted to receive the screws 35a and 36a, shown inFig. 19. The screw 35a holds a block member 3?, see Fig. 19, in which issecured the circular spring member 38, and a cut-out portion 39 permitsthe disc 30 to rotate a short clistanceto'the right or left of the blockmembe 3?. On the opposite side of the unit is located the spring stopmember 40 which limits the movement of the free ends of the said spring.Another slot 4!, similar to slot 39, is provided to allow the disc 3!)to rotate a short distance to theright or left of the screw 3611. Itwill thus be seen that the disc 39may be rotated to the right or left onthe shank33 of the pinion member 24 within the limits of the slots 39and H; and inasmuch as the spring=38 is secured in the block 3.1 whichis in turn fixed on themember 34; the disc 3'0iwi'1l always return toaneutral position', as shown in'-.F'i'g; 19 when not -otherwise heldfromzso doin g. In the same disc 3|i'there is another openingcomprising; an oblique angled. slot 42'ithroughwhich: projects a pinxdS;see Fig..20, which isattached to a.slide member lflislidably'locat'ediinzslide-way. 451 in the member: 3.4 Theslot id: acts asaa.cam: track so" thatawhen the' disc 3 3? is. rotatedsto the right orrleitaround the pinionmithe pin itii'willmove the :slide member. to; theleit'inthe slideway. 453 Also locatedonathe periphery. of the member 34is a'..plura1ity. of slotslifi; also. shown: in dotted linestain Fig;19; It willthus be seen: that when the. disc. as; is rotated to. the:right: orleftrthese slotssfla. will be: exposed such that apawl imemiberattached to the; unit l3, as will ibe-.-described later, could;beengagedi'. in; the slots. thereby locking the-member3.4ifromsturningfurthe1z. Bfy a,.iurther. inspection'iofrFi'gsnZOandr26,it will becobservedthat themember 34 is provided. with asquareahole 4-1and that the; corresponding por tion.3;3: 0f the shank otthexpinion 24is squared to fitthisrsquare-hole; therefore it follows thatwhen-themember 34 1s locked against rotation,

the same is'truepregarding. the pinion. 24: In Fig: 2-1, thexmemberiii-has been removed to:dis-. close the structure directly beneath,. andwhich incrudes a disc 43 onwhich isamountedi and a parttthereofi an.open rin portion? 4i provided with tappedscrew holes 55'which are adapmdtoxreceivethe: screws 5| which secure the member- 34 thereto;Ittwillthus be seen that when the disc 48 isrotatedto the rightor left,the member 34-wi1l also rotate and the inien 24 will. move-likewise. InFig; 231 have shown. a notched member 52 which is secured to thewormwheel 2| by means of the screwsz53. engaging in the tapped holes 54located in the worm-wheel 2|. Therefore; due to theiact that the member52 is positively securedtothe worm wheel 2 it follows-that when the wormwheel 2| moves, the

member. 52." must move: also. Itwill thus beseen that insorder toeflecta drivebetween theworm wheel 2 and the pinion 24 the member 52-.must be. lockedwiththe member 34 having I the square hole 41engagingwvith the squared portion-330i the. pinion 24.- To produce thiscondition, I'have devised the following intermediate: structure. Betweenthe two open ends of the portion ili on the disc :68 I have pivoted thedog. member. shown in Fig. 27 and Fig. 21, Fig. 2!? being. a. reverseside view from that shown inFig. 21 in. which it will be observedthat.the dog member 55. is provided with trunnion portions 56. located oneither side. of the dog member 55, the lower side, as viewed in'Fig. 22,being. pivoted in. the hole 51. located in the disc 48 and the upperside. of which; is. pivoted in the member, 313. Located around the.inner periphery 59, see-Figs. 21.to

23inclusive, of the notched..member 52 is a split ring. friction-member.fill, the openends of which are. provided withupstanding pin. members5'! which proiect up into the opening 52. in the slide member 44,shownin Fig. 20. The inner sides of the opening. 62 comprise camsurfaces 63. The split ring friction member Eflis maintained in anexpanded position against the member 52' by means of the spring 64.Under these conditions, if.the split ringmember E0. is not otherwiseacted upon, itwillturn in the notched member 5.2 and the member 34 willnotrevolve when the member 52. turns; but if; the split-ring member v601is .ex-

panded, themember fi l 'will become. frictionally locked withthewormwhee-1 2| and" wi11'- turn with-it. Byan inspecti'on'of Fig. 27 it willbe noted that the-doe member 55 is provided with alower pin portion 65which isadapted to engagein-thecurved open ends of' the split ring 60.The dogmember-55 is further provided with pawl portions 66; see-Fig.27', which are adapted to engageagainstthe notched portions ofmember'52when the dog member 5.5"is pivoted in the holesl'fi and. 53 inthe member 48* and 34' respectively. This; condition takes placevvhenthe worm wheel is. turned from right to left unless the dog member 55.is acted upon from other ape paratus to prevent it. from pivoting fromright to left. Inother. words, ifv the dog member'55 is maintainedintheposition shown in Eig..21', the disc =38. will not lock up with the disc3'41 If there, is nothing to. prevent the. dog. member 55 from-pivotingtothe rightlor left it will engage, by means of the pawls .66.withthenotchedmember. 52; thereby looking the worm wheelll' with the member34 and pinion .24.

As shown inEig. 19, the disc.3|).normally covers the slots 45. in themember 8% and until the .disc..'30 isrotated sliehtlyno. ioreignmattercan engage in these slots iiwhich would cause. the dog. mom.- ber. 55.to pivot, butwhen the disc 301s interrupted or retarded. inrotation-the following takesplace. The. cam slot zicausesthe slideM'tomove tothe left, as viewed in Fig. 20, and as thecamsides 63 ofthe slidemove convergingly they contact the open ends of 1 the split frictionring Bilpermitting it-to rotate freely in the. notched member; 52:;therefore the pins fil do not engage the-dog member 55, with. theresultthatlthe' d0g;,55.-doesnot pivot and: engage one "of itspawl portions 55with the notched member 52;

In otherwords; whenever the unit, as-discloscd in Figs 18 to 27 inc1usive. are in apositioniwith the slots 3| and 4'6.- in. register, theadjacentpin: ion 2 is directly engaged withtheaworm wheeldl and: willvrotate in. the same direction thatathe worm wheel is turned by themotori; Ii-themo+ tor.

As before stated; the. opposite side of the unit disclosed in Figs.1.8:' to 271s. exactly the samesand operatesinthe. same manner. Thecontrol; of this unit depends entirely on the: outside inter..- ferencewith the disc 3 which is the; same inoperation from either side of=theunit and-this is controlled from one rod or shaft lfi'mountedon theupper. portion of the automobile door. When theshaft Hi lSl raised. orlowered, the side ofthe unit illustrated in Figs. 19. to 25 is affectedand operates the window sash; and when the shafttli is rotated t e otherside of the unit; not specific= ally described, is contacted and made tooperate the ventilator. as will nowbe described.

I will'firsti describethe mechanism and operation oi'the apparatusconcerned With-theraising and lowering of the windowsash H. Located inthe unit lagbetweenthe side portions 22. andfit is a unit 15 andadjacent thereto is electrical switch. 'iiitthe switch being. plvotediihthe unit. It by means oi-the-pin 11.. This switch is'operatedby'bcththesash M and the ventilator It. Inithe case oi the ventilator;the. central-switch -lever:"!.8 pivots-to the-rightor left,iorwardiandreverse,

and the body of the switch is held in a neutral position, as shown inFig. 6. When the switch "I6 is operated by the window pane I I, thereverse is true; the switch'lever I8 is held in a neutral position asshown in Fig. 6, and the body of the switch is pivoted to the right orleft, forward and reverse. Further along in the description, the detailsof the inside of the switch will be described.

On the side of the unit I have provided a vertical slide member I9 whichis provided with an attached block member 89 which projects through theopening 8| provided therefor in the side 22 of the unit I3, see Fig. 3.The rod I9 is secured in the block such that when the rod 19 is raisedor lowered the slide I9 will respond likewise. Also located in the slide79 are recessed cam track 82 an 83. Engaging the cam track is ahorizontal sliding dog lever 84. It will be apparent that when the slideI9 is raised or lowered from the neutral position shown in Fig. 6, thedog slide member 84 will be slid to the left-hand side. As shown in Fig.6, the dog slide 8 3 is in the righthand position being normallymaintained there by means of the spring 85. In this position the dog endof the slide 84 is engaged with the clutch unit previously described. Inthis position, as shown in Fig. 6, the end of the dog has entered one ofthe slots 3! of the disc 39 thereby stopping its further rota-tion; andas the member 39 continues to rotate, one of its slots 49 rides underthe end of the dog slide 94 at which time the dog slide advances intothe slot 46 thereby bringing the member 34 to rest. While this actionhas been taking place, it will be noted by an inspection of Fig. 6, thatthe disc 30 in its slight rotation on the pinion 24 has caused the slidepin 43 to cam outwardly in the cam slot; therefore the slide member 44is thrown to the left from the position shown in Fig. and the dog member55, which previously was tipped and engaged with the notched member 52,has been returned to a neutral position thereby disengaging the drivingworm wheel 2| from the pinion 24.

Attached to the switch body I6 is a lever 8'. which is pivotally andslidably engaged with the vertical slide member I9 such that when theslide 19 is raised or lowered, the switch body "I6 will pivot on the pin11 thereby opera-ting the motorin a forward or reverse direction. If itis now assumed that the rod 19 is either raised or lowered,

it will be apparent that the slide dog member 8 3 will be withdrawn fromthe clutch unit, in which event the disc 39 will snap back to thepositiOIl shown in Fig. 19. Consequently, the slide member 44 returns tothe position shown in Fig. 20 thereby permitting the split friction ring69 to engage the notched member 52 which is directly connected with theworm wheel 2| and thereby causing the dog 55 to engage with said notchedmember and, as previously pointed out, engaging the pinion 24. Thepinion '24 will now revolve either clockwise or counter-clockwise, thedirection depending upon which way the switch I5 is tipped by means ofthe lever 87.

By an inspection of Fig. 3 it will be observed that the pinion 24 isdirectly engaged with the rack I4 which is connected with the windowsash II; therefore, when the pinion 24 rotates, the rack mOVes in averticaldirection, either up or down.

In order that the mechanism will not be damaged, jammed or otherwisedisplaced when the window II has been opened or closed to its full limitby a careless operator who does not release the control mechanism intime, I have provided 7 an automatic mechanical cut-out attachment whichwill act at the properltime to operate the slide 19 and neutralize theswitch I6 thereby discontinuing the course of power. I have attainedthese ends in the following manner as I will now describe: Attached tothe outside of the unit I3 is a pivoted bell-crank lever 90 having ahorizontal arm 9| which is provided with an elongated slot 92, bettershown in Fig. 3, in which is slidably engaged a pin 93 the fixed end ofwhich is attached to the block 89 located on the slide I9. On theperpendicular end of the bell-crank lever 90 I have provided a pivotedroll member 94. It will thus be apparent that when the bellcrank lever96 is oscillated, the slide member I9 will be pushed up or downtherebytilting-the body portion of the switch It and thereby stoppingthe electric motor I'I. To eiTect this'result, I have placed at theproper position, a cam member 95 on the lower portion of the rack I4such that when the rack and window II reach a position approximating theclosed position, the cam 95 will move the slide 19 to a neutralposition. In a similar manner, I have placed a second cam member 95,Fig. 5, on upper end of the rack I4 so that when the window is beingdropped, or opened, the cam 96 will engage the roll 94 and throw thebell-crank lever 90 in the opposite direction thereby returning theswitch body portion to a neutral position.

With special reference to Fig. 5, I have shown an elongated slot 91through which operates a bolt connected with the window sash II. Theelongated slot 81 allows a small amount of backlash so that the motorhas a chance to assume its full load by the time the rack I4 actuallystarts to operate the window II. Under normal conditions this is notnecessary but under freezing conditions when the window II may possiblybe stuck with frost or light ice it is a great advantage, as the suddenforce being applied quickly starts the window moving when otherwise themotor might not have built up enough force to effect this result. Itwill thus be seen that by raising or lowering the rod III the window I Imay be raised or lowered, as the case may be, and automaticallystoppedat the end of its travel, also that the window will automatically cometo a stop at any time pressure is released from the rod 70 therebyallowing the slide I9 to return to the neutral position shown in Fig. 6.

When it is desired to operate the ventilator I2, the rod I0 isoscillated to the right or left. By an inspection of Fig. 3, it will'beobserved that the lower end of the rod III which continues into theblock is threaded so that the rod 10 may turn or pivot from side to sidein the block ,8, but when moved up or down the block 80 will also moveup or down, but when the rod III is pivoted in the block 80 there is noeffect on said block. Above the block 89 I have provided a bracket 98through which the square portion of the rod I0 passes, and in saidbracket is located a segmental gear 99. the toothed side of whichengages through an opening I provided in the side 22 of the unit I3. Inthe unit I5 is a vertical shaft III! on which is secured the plate I02which is provided with pins I03 adapted to engage the teeth of thesegment 99. It will thus be apparent that when the'rod III isoscillated,

the plate I92 will likewise oscillate. Secured to shaft IGI, Fig. 8, isa cam member I94 which operates a lever I95 which is pivoted at I06. Byan inspection of Fig. 8, it will be apparent that when the cam I94oscillates 'to the right or left "the lever-I "will swingon the pivotI06. free end "I01 of the lever I05 comprises a ball and socketr-COIIIXCCtiOll with a horizontally located The sliding 'dog member I03similar to member 84.

This ;slide dog.-member .108 is engageable with the left-hand side ofthe unit shown in Fig. 18, .the details :of whichzare identical with therighthand side previously described. It will thus be apparent thatthe'clutchapparatus concerned in the'unit shown in Fig. 18 willoperatein :the same manner and be controlled in the-same man- :nerby.theilever I08 as was the case in connection withlever-M. The spring I09normally holds thealever I03 to the right-hand side, as viewed inFig.-8,=in a like mannerto the spring 85in I connection :with lever B ltherefore,- it .will beapparent that when the dog lever I03 is withdrawnfrom its position shown in Fig 58, the worm wheel of theresilientlever'l I0 which is pivoted at Ill to the-cam IN, the other end ofwhichis pivoted to the upper end of theswitch lever I8. In thiscase-when the rod l -0 isswung or pivoted'to the right 'orleft, the bodyportion of the switch "It;- is'in a neutral-positiomas shown in "Fig. 6,and the lever moves in the body of the switch thereby making theelectrical connections-with the 'motor I'I to start, stop, and reversesame.

In connection with the ventilator mechanism, I have'prov'ided anautomatic mechanical cut-out to stop the apparatus when the ventilatorhas reached-its limit of movements'as will now be described. Locatedunder the top of the casing of the unit I3 is a-slide member II2 whichis provided with stop members [I5 and IIS extendingupwardly-through-slots I I-5a and I IBa respectively in thetop 'o'fthecasing of unit I3. Springs "H511 and H61) respectively hold the slide ina normal position. Located on an extension portion a of the rack 25is'a'stop member I II which engages the stop members I I5 and H6 whenthe rack 25 reachesits limit of travel either to the right or to theleft. In Fig. 10, I have shown a plan view of the-extreme leit'endof theslide I I2 in which is shown an open area I I8. On the upper side of theplate I02 fixed to the-shaft IOI is located a vertically positioned pinI I9 which projects upwardly through the area II8'in the slide II2-andthrough an opening I20 provided in the topside of the unit I3. This areaI I8 is outlined bythe'cam" surfaces I2 I-and I22 and end portionsInland I24. The'pi-n H 9 operates in this area II8 and'is so'locatcdthatwhen the rack stop member III contacts with the slide stop member II5,the end portion I24 engages the pin 9 and turns the rod I0 to a neutralpositionthereby stopping themovement of the ventilator, and in a similarmanner, when therack stopmember I I1 moves in the reverse direction tothe end of its normal travel it engages the slide stop member H6and-thereby pulls the slide II2 to the right contacting the end I23 ofthe opening H8 reversing the rotation of the rod I0 and again re turningthe connected mechanism to a neutral position. Figs, 28 to 31 inclusivedisclose a simple switch fixture from which the rod I0 is operated andcomprises the following: I comprises the frame of the apparatus which isdirectly attached to the structure of the automobile door. Right-angledbrackets I'3I and I32 .are'secured'tothe'frame I30,.aszshown inFig.';31, and'anothermember I33 is alsosecured to thefra-me I130 atninety degrees thereto. !The member: I33 is provided with ahorizontal-slot Itfiat its rearportion-through which .is slidablylocateda ,pinor finger-control lever I35. The pill? I35 is pivotally fixed inauniversal knuckle member I 30 ytogwhicln is attached ashaft 10a whichiis-a continuation of the previously referred to shait'IIl. In thefaceof the frame L30 are located dour-slots I40 each of which arelocated at ninety degrees to each other. These slots I40 are adapted toreceive the finger lever orpin I35 whichis pivotally mountedin theuniversal knuckle memberIBB. It will be apparent from an inspectionofthe drawings that when the finger member I35 is moved up or down, orfrom left to right, the rod l-0will move likewiseand rackmembenZ-bawhich engages with a similar slidable cam member I5I such-that due to.the spring I52 the slide I5I will slightly crowd-the rackZE-andmaintain a force to the right-hand side after the rack, hasbeenstoppedby means of the slide} I2. In. other words the cam-facesonthe members I50-and I5I maintain a pressure againstthe rack, gears etc.up to the ventilator I2 after the mechanism iselectricallydisconnectedthereby holding the ventilator window I 2 in atightly closed position until further operated upon by the apparatuslocated in the unit I3.

It is also-true that the main drive, clutch apparatus and switchingmechanism cannot operate except when the lever I35 ismoved and it-isimpossible fcr this lever to beoperated in more than one position at atime.

;-Figures 11 to 17 inclusive indicate the details of the-switchlfi, inthe position shown in Fig. 1-2, the electrical current is oil; in. otherwordsthe switch is in a neutral position; the contacts are numbered tocorrespond with the circuit diagram shown in Fig. 32. -When the rodmember 10 is rotated to the left .orright-hand side-theswitch memberimis piVoted :accordinglyon .thevpin I1 and the electric motor- I!is---energized .either'for- Ward or reverse, as the-case may be, and dueto the'fact-that-the clutch portionwhich operates the pinionzzt and rack2iithe ventilator is operated.

When-the switch member is inthe neutral'position shown in Fig. 12, andthe rod 'I0-,is pushed up or down, the body portion I6 of-the switchpivots .on the pin "I I. and the motor is again energized rightorleft-hand, as the. case may be. In this action the clutch member 8.4.iswithdrawn releasing the clutchpinion .24 which raises ,or lowers thewindow sash rack member I4. In this position,1 theclutch member 'IIIBisengaging the clutch thereby locking the pinion-2 6.
